DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The term “interaction activity information” as used herein refers to information about a function that may be used interactively between connected apparatuses. For example, according to such an interaction function, when a first apparatus and a second apparatus are connected to each other, a function of the first apparatus may be performed by the second apparatus, or a function of the second apparatus may be performed by the first apparatus. An interaction activity list is one embodiment of the interaction activity information. Hereinafter, information about the interaction function will be referred to as an interaction activity list.

FIG. 1 is a block diagram of an interaction activity list generating apparatus 110 according to an embodiment of the present invention.

Referring to FIG. 1, the interaction activity list generating apparatus 110 includes an interface unit 111, a list generating unit 112, a displaying unit 113, a controlling unit 114, and a storing unit 115.

The interaction activity list generating apparatus 110 is connected to an external apparatus 120 via the interface unit 111. A connecting method between the interaction activity list generating apparatus 110 and the external apparatus 120 will be described in detail below. The interface unit 111 receives information about a function that is capable of being performed in the external apparatus 120 from the external apparatus 120. The information about a function that is capable of being performed in the external apparatus 120 includes metadata regarding functions, performances and limitations of the external apparatus 120. The metadata includes the functions, performances and limitations of the external apparatus 120, but is not limited thereto. The metadata may include any information as long as the information can be used to generate the interaction activity list. In addition, the information about a function that is capable of being performed in the external apparatus 120 may further include controlling signals regarding functions and performances of the external apparatus 120. If interaction activity list generating apparatus 110 receives the information about a function that is capable of being performed in the external apparatus 120 after requesting the external apparatus 120 for the information about a function that is capable of being performed in the external apparatus 120, the information about a function that is capable of being performed in the external apparatus 120 may further include authorization information with respect to the controlling signals of the external apparatus 120. The interface unit 111 transmits the metadata of the external apparatus 120 to the list generating unit 112.

The list generating unit 112 generates the interaction activity list using the metadata of the external apparatus 120, which is received from the interface unit 111. In detail, the list generating unit 112 selects functions of apparatuses including the interaction activity list generating apparatus 110, which may be performed by the external apparatus 120, with reference to the functions, performances and limitations of the external apparatus 120, which are included in the metadata. Then, the list generating unit 112 generates the interaction activity list using the selected functions, and controlling signals corresponding to the selected functions from among the received controlling signals. The generated interaction activity list is stored in the storing unit 115.

The controlling unit 114 selects one external apparatus 120, from among external apparatuses that are searched for via the interface unit 111, generates a connection request signal, and transmits the connection request signal to the interface unit 111. The interface unit 111 transmits the connection request signal to the external apparatus 120. Then, when the interface unit 111 receives connection authorization from the external apparatus 120, the interaction activity list generating apparatus 110 and the external apparatus 120 are connected. It is possible that the external apparatus 120 may not allow the interaction activity list generating apparatus 110 to be connected to the external apparatus 120. When the external apparatus 120 allows the interaction activity list generating apparatus 110 to be connected to the external apparatus 120, predetermined information about the interaction activity list generating apparatus 110 may be stored. The stored information may be used when the interaction activity list generating apparatus 110 is reconnected to the external apparatus 120.

According to another embodiment of the present invention, when the external apparatus 120 access an interaction activity list generating apparatus 110 within a predetermined range, the interface unit 111 connects the external apparatus 120 to the interaction activity list generating apparatus 110. According to the present embodiment, only when the external apparatus 120 physically contacts the interaction activity list generating apparatus 110, the external apparatus 120 may be connected to the interaction activity list generating apparatus 110. In this case, the external apparatus 120 does not have to be searched for and selected.

The displaying unit 113 displays the generated interaction activity list. In addition, when the connection between the external apparatus 120 and the interaction activity list generating apparatus 110 is released, and then the external apparatus 120 and the interaction activity list generating apparatus 110 are reconnected, the displaying unit 113 displays the interaction activity list related to the external apparatus 120 and the interaction activity list generating apparatus 110, which is stored in the storing unit 115. The displaying unit 113 may include a touch screen.

When a user selects a predetermined list in the interaction activity list displayed by the displaying unit 113, the controlling unit 114 determines a signal regarding a function that is selected in the displayed interaction activity list. Then, the controlling unit 114 transmits an instruction that the external apparatus 120 performs the selected function to the external apparatus 120 via the interface unit 111.

According to an embodiment of the present invention, after the interaction activity list generating apparatus 110 generates the interaction activity list, the interaction activity list generating apparatus 110 may transmit the metadata regarding the functions of apparatus including the interaction activity list generating apparatus 110, to the external apparatus 120. Here, the functions may be used in the external apparatus 120 interactively between the apparatuses including the interaction activity list generating apparatus 110 and the external apparatus 120. Alternatively, after the apparatuses are connected to each other, the apparatuses may exchange metadata regarding respective functions of the apparatuses and may generate respective interaction activity lists.
